Summit X250e Series
Technical Specifications
Designed for High-Performance
Network Application
Exceptional Policy-based QoS with Advanced
Traffic Management for Converged Applications
Summit X250e provides eight hardware queues per port to support
granular traffic classification with bandwidth allocation. 1,024 centralized
classifiers per 24-port block can use information from Layers 1 through 4 to
prioritize and meter incoming packets at line-rate. When metering traffic,
the switches can drop out-of-spec traffic or flag it for later action. To
expedite upstream traffic handling, a packet’s classification can be carried
forward with Layer 2 (802.1p) and Layer 3 (Diffserv) markings. Summit X250e
provides advanced traffic management features that support the
high-quality triple play of voice, video and data services.
Efficient Management to Handle Convergence-
Driven Network Changes
Universal Port—VoIP Auto-Provisioning
Summit X250e sets the stage for convergence applications by allowing
enterprises to add new access devices in a non-disruptive plug-and-play
fashion. Voice and wireless services can be easily implemented without
major network upgrades. Summit X250e supports the automated
provisioning of VoIP using Link Layer Discovery Protocol (LLDP) and the
event-based command scripting capability. It allows dynamic configuration
of voice VLANs and QoS. This auto-configuration capability allows you to
configure VoIP phone settings such as voice VLAN settings, call server IP
address configuration, etc. (see Figure 3). This level of simplicity in
managing network changes can reduce operating expenses.
Power over Ethernet (PoE)
Deployments of IP Telephony depend on reliable, consistent power from
the Ethernet jack. Summit X250e-24p and Summit X250e-48p are the
basis for a reliable LAN telephony infrastructure with fully redundant
resiliency to match the failover requirements for latency-sensitive services
like VoIP phones. With Summit X250e-24p or 48p, deployment of powered
LAN devices is quick and easy with its support of the IEEE 802.3af standard
and full Class 3 power availability on all ports, backed up 100% by the
EPS-500 redundant power supply (Summit X250e-24p). Summit X250e-48p
can provide up to 370W of PoE power and can be increased up to 740W of
PoE power to provide full 15.4W Class 3 devices on all 48 ports by adding
an External Power System (EPS-C and EPS-600LS).
Voice-Grade Connections
Granular QoS, low latency and low jitter enable voice-quality connections.
Summit X250e supports a range of QoS technologies that can prioritize
and predictably handle high-priority traffic policing or rate limiting on
ingress, 802.1Q tagging and Diffserv marking, and shaping on egress with
eight queues per port. The Extreme Networks tradition of building products
with low latency and jitter continues with the Summit X250e series.
Comprehensive Network Management
As the network becomes a foundation of the enterprise application,
network management becomes an important piece of the solution.
Summit X250e supports comprehensive network management through
Command Line Interface (CLI), SNMP v1, v2c, v3 and an embedded
XML-based Web User Interface, ExtremeXOS ScreenPlay™. With a variety
of management options and consistency across other Extreme Networks
modular and stackable switches, Summit X250e series switches can
provide ease of management for demanding converged applications.
Extreme Networks has developed tools that simplify and help in efficiently
managing your network. Ridgeline™ network and service management
provides fault, configuration, accounting, performance and security
functions, allowing more effective management of Extreme Networks
products, solutions and third-party devices, in a converged network.
For carrier networks, Ridgeline enables the shift from reactive circuit
monitoring to proactive service management. The key features integrated
into the Service Advisor Feature Pack unify service fulfillment, service
assurance and service engineering to enable carriers to more effectively
manage next-generation residential triple play, business Ethernet and
Ethernet mobile backhaul services.
Advanced Routing Capabilities for the Edge
Summit X250e supports advanced protocols for an efficient and productive
network. Summit X250e switches provide static and RIP routing for simple
IPv4 and IPv6 Layer 3 deployment. An optional ExtremeXOS Advanced
Edge license extends the feature set to include other important edge
functions such as:
• Edge OSPF for much greater extensibility than RIP can provide
• Edge PIM sparse modes for routing of multicast streams
• Policy-based routing
• Virtual Router Redundancy Protocol (VRRP) to provide routing
redundancy
